Zirconyl nitrate, basically nitrate precursors were highly soluble in water.

Joaquim Mª Rius Bartra

I think, that the best source is ZrCl4/SiCl4. Gives pure oxides because product are HCl(aq). The reaction is the hydrolysis: ZrCl4+H2O>ZrO2+HCl.

Prof.(Dr.) R.C. Chhipa

Try Zirconium Sulphate in moderate condition.
